Phänotypische und genotypische Charakterisierung der ENU-induzierten Mausmutante SMA002 als Tiermodell für Wachstumsdefizit und Hyperaktivität
… background. As the main phenotype of SMA002, an abnormal behavior combined with reduced body weight was revealed. The mutant phenotype showed complete penetrance in all generations analyzed. Abnormal behavior, as the most prominent phenotype was characterized by the occurrence of restlessness and …

Edge-Based Anomaly Detection for IoMT: A Lightweight Unsupervised Model and SIEM Integration
… creates a detection challenge: how to identify abnormal behavior early without adding heavy security tooling or sending large amounts of telemetry to a centralized system.This thesis presents the design and evaluation of an edge-based, unsupervised anomaly detection pipeline for IoMT telemetry, …

EXPLORATORY GRAPH BASED BOT DETECTION APPLICATION ON REDDIT SUBNETWORKS
… machine learning systems to classify abnormal behavior. We focus on abnormal term usage as a markerof bot behavior around politically charged language regarding the Covid-19 pandemic on Reddit. We look at multiplex networks abstracted from different subreddits around six terms. We then …

Log file anomaly detection using knowledge graphs and graph neural networks
… files contain valuable information for detecting abnormal behavior. To detect anomalies, researchers have proposed representing log files as knowledge graphs (KGs) and using KG completion (KGC) techniques to predict new facts. However, current research in this area is limited, and there is no …

Closed-loop bladder function control for rats using optogenetics
… and electrically stimulate the heart only when abnormal conditions are detected. This thesis presents a closed-loop bladder function control system for rats. The bladder activity is monitored using a novel sensor in a less invasive manner than the traditional pressure sensors. A neuromodulation …

On the Impact of Android API Evolution on Education Materials
… apps from these new labs were further tested for abnormal behavior on a variety of Android devices. Results from analyzing all feedback and observations show that despite all measures taken to future-proof these labs, Android device and API evolution continues to vastly outpace third-party Android …

Using High-level Synthesis to Predict and Preempt Attacks on Industrial Control Systems
… along with a supervisory process to monitor the behavior of the plant. Furthermore, a copy of the software and a model of the plant are implemented in hardware in order to estimate the system's future behavior. In the event of an attack, the hardware can successfully identify the plant's abnormal …

Continuous estimation of cardiac output and arterial resistance from arterial blood pressure using a third-order Windkessel model
… many cases unable to determine the causes behind abnormal behavior of the cardiovascular system because they lack frequent measures of cardiac output (CO), the average blood flow out of the left ventricle. CO is monitored via intermittent thermodilution measurements which are highly invasive and …

Verification of Cyber Physical Systems
… that would aid as monitors in detecting abnormal behavior of the software. Potential invariants were extracted which had to be validated. The investigation attempts to uncover the possibility of performing this method on existing Software verification platforms. This was accomplished on …

Noise-induced cochlear neuronal degeneration and its role in hyperacusis -- and tinnitus-like behavior
Perceptual abnormalities such as hyperacusis and tinnitus often occur following acoustic overexposure. Although such exposure can also result in permanent threshold elevation, some individuals with noise-induced hyperacusis or tinnitus show clinically normal thresholds. Recent work in animals has …

Detecting Methane Anomalies from Satellite Data in the Arctic
… differences between these values could indicate abnormal behavior and even environmental changes, such as new methane sources, in the research area. For this anomaly detection TROPOMI WFMD v1.8 dataset in the Arctic region for the summer and spring seasons of 2018--2023 is used. The main focus of …

Hunters' responses to chronic wasting disease: specialization, social trust, and perceived risk
… in several states and provinces. CWD causes abnormal behavior, emaciation, and death in all infected animals. Although CWD has not caused human health problems, transmission to humans cannot be dismissed. Little is known about the extent to which hunters: (a) would hunt in other states or …

The Role of MEF2 Transcription Factors in Neocortical Circuit and Synapse Development In Vivo
… causes aberrant circuit function and ultimately abnormal behavior linked with neurodevelopmental disorders such as autism. Therefore, a neuron must contain cellular machinery to regulate synaptic connectivity. The activity-dependent Myocyte Enhancer Factor-2 (MEF2) transcription factors - MEF2A-D …

Single and Pair Housed Chacma Baboons’ (<i>Papio ursinus</i>) Response to Caregivers’ Use of Species-Specific Behavior
… captive primates suffer from stereotypical or abnormal behavior which can be reduced by implementing enrichment protocols. There is, however, often spatial or economic limitations to facilities’ enrichment programs, and implementing the most beneficial and cost-effective enrichment is therefore …
